My 7-year-old has a severe peanut allergy and a much milder tree nut allergy (among other foods). Our solution...we don't fly Delta and we don't fly Southwest (or AirTran any longer in case catering gets switched).

While you can remove serving peanuts from one flight, I can't tell you how many times I've seen a "rogue" peanut wedged in a seat, on the floor, in the seat back pocket, etc. Not to mention the thousands of cycles a/c have gone through with the peanut dust still circulating even if you don't serve them on one flight. The peanut residue can exist on a surface for up to six months.

We generally fly JetBlue when traveling as a family (sadly leaving my DL miles to continue piling up), where we're granted pre-board access to thoroughly clean his seating area. We always reserve the last or next-to-last row and the flight attendants kindly make a generic announcement to the last few rows that a peanut allergy sufferer is on board and if they brought peanut products on board, they would be glad to re-seat them. We bring 2-twin packs of epinephrine, buying us close to 60 mins of treatment in the event of an exposure.

I am partially glad Delta is implementing this policy, but at the same time, those who truly suffer a life threatening allergy still shouldn't fly Delta. So why then "punish" the rest of the airplane.

That said, to a previous poster: If you do bring peanut products on board and the announcement is made on your next Delta flight, I hope you'll seriously consider waiting until you land to consume the product. I bet the 90+ minute delay you'll experience from the emergency landing will be a much bigger inconvenience than snacking on Biscoff's instead!
